FRANKLIN H. LUMMUS, OF BROOKLYN, NEW YORK.

COTTOIN-GIN.

SPECIFICATION forming part of Letters Patent No. 266,376, dated October 24, 188:2,

Application filed April 4, 1882.

To all whom it may concern:

Be it known that I, FRANKLIN H. LUMMUs, a citizen of the United States, residing at Brooklyn, in the county of Kings and State of New York, have in vented a new and useful Improvement in Cotton-Grins, of which the following is a specification.

Myinvention relates to that form of cottongin in which a series of ridges or blades is used,

in combination with a saw and brush-cylinder,

to whip and clean the flake; and my invention consists ofaprculiararrangementof the blades or ridges, whereby the sand, trash, &c., are free to drop into the mote-chamber of the gin.

111 the drawings, Figure l is a vertical section of the entire machine with my invention applied thereto, and Figs. 2 and 3 are 'views of a modified form of the series of blades or ridges.

Similar letters refer to similar parts throughout the several views.

The letters AA represent the frame-work ofa cotton-gin; B, the mote-chamber; (J, the lintliue; D, the hopper; E, the ginning-saws, and F the brush-cylinder. The above-named parts are all old and well known in the art, and I lay no claim to them or to their arrangement.

H represents a board or bed in which the whipping ridges or blades 2' t are secured. In the upper surface of this bed H, I cut grooves, which are adapted to receive the inner edges of the whipping-ridges and to hold such ridges in position. This whole structure is secured (No model.)

to theframe-work of the gin by means of the brackets h, and I have obtained the best results when the whipping-bed is placed as near as possible to the point of contact of the ginningsaws and the brush-cylinder, for by this arrangement it is almost impossible for naps and curls to form in the flake of cotton during its passage from the saws to the whippingbed, and an exceedingly line staple is produced. The ridges or bladesi i are mounted in the bed H at such an angle thatwhen the bed is placed in position theirouter edges are depressed from a horizontal plane, and this arrangement of the blades constitutes my invention, the spe cial advantage of which is that all sand, trash, &c., are free to drop into the mote chamber of the gin.

In Figs. 2 and 3 I show a whipping-bed in which the edges of the blades are concentric to the periphery of the brush-cylinder instead of being tangential thereto, as in Fig.1.

Having thus described my invention, what I desire to claim and secure by Letters Patent 1s- A whipping-bed having longitudinal parallel ridges or blades, the outer edges of which are depressed from a horizontal plane, substantially as described.

FRANKLIN H. LUMMUS.
